Mazda Q&A

1993 Mazda MX-3 Question: How may a non-mechanic replace oxygen sensors on a Mazda MX/3?

My 1993 MX-3 failed the low idle hydrocarbons test at the DMV. Can anyone help me with this problem?
(I am unemployed and cannot afford the $800 estimate that a garage gave me to replace the spark plugs and the oxygen sensors. I was told they needed to be replaced due to oil leakage.)

FIRST THING to do BEFORE spending any mony on car is to educate yourself on the emissions laws!!!! Find out if they allow a 'waiver' if , after you spend a certain amount , it still doesn't pass emissions. Find out how they require the repairs to be 'documented' etc. DEQ , or DMV online in your state may have some info.
